**Japanese Yen to U.S. Dollar Spot Exchange Rate Chart**

The chart, sourced from the Board of Governors of the Federal Reserve System (U.S.), shows the Japanese yen to one U.S. dollar exchange rate over time. The x-axis represents the years from 1970 to 2022, while the y-axis shows the yen value ranging from 40 to 360 yen per dollar. The data line indicates fluctuations in the exchange rate over this period.

**Trends Observed:**
- In the early 1970s, the yen was above 300 per dollar.
- A significant appreciation of the yen occurred in the mid-1980s, dropping to about 130 yen per dollar.
- There were fluctuations around this level until the mid-1990s when the yen reached its strongest level of approximately 80 per dollar in the late 2010s.
- The yen then weakened again, trending upwards toward 150 yen per dollar by 2022.

**Discussion Questions:**
1. How many yen could you get per dollar at the earliest date shown on the chart? Explain.
2. How many yen could you get per dollar at the most recent date shown on the chart? Explain.
3. Has the dollar appreciated or depreciated in value over time? Explain.

The chart illustrates the historical fluctuations and trends in currency exchange, providing insights into economic events, policy changes, and market reactions over five decades.
